Did the job for a fraction of the price
Needed the tool to adjust the jake brake, none of the local stores had it. Ordered it on Amazon had it in 2-days, fixed our truck and back on the road by Monday.

Checked and is spot on 7mm. works just as well as my Cummins tool but at a 1/4 the price. Recommend this over the Cummins tool

Wrong measurement
4.1 feller gage was correct when using a caliper to measure but the 4.6 mm feeler gage was actually reading 4.45mm

Poor Quality
measures 6.95mm and the picture shown in the ad is not what the tool looks like
